I just hit lv31 and since I'm leveling my summoner to lv50 3 question bug me every time I play with Carby. 1. Do Carbuncle use TP? Like my PUP i have TP info macro in all my summoner macros. 2. What are the elementals used for? I bought them all from AH and light buff and quick fire summon backup is all I use. 3. What skill should a summoner be to start the level capped avatar fights? My skill is close to 80 and i think i read somewhere 68 is the Lev 20 cap....Any help will be appreciated.

1. Do Carbuncle use TP? Like my PUP i have TP info macro in all my summoner macros.

All avatars have the same behavior regarding TP: It is used to boost magical moves only, and does not affect physical moves. For example if you use Poison Nails, it will not consume Carbuncle's TP. However, if you use Healing Ruby or Meteorite, they will both consume the TP and their accuracy/potency will be affected by it.

They are used for basically nothing, except Elemental Siphon. Folks have struggled to find uses for these, but they are generally pretty lame.

I believe the cap at 20 will be about 93 skill. You should absolutely cap it before doing those fights, as it's very possible, even likely I'd say, that you will be hit once or twice while attempting to resummon Carbuncle. Summoning skill helps your interruption rate immensely. Sadly, that's about all it's good for until you reach the upper levels and start getting equipment that can push you well over the cap for skill.

If you're aggro'd without Carby, they can be used as a disposable meat shield due to their psuedo-instant casting time, buying enough time to get away.

Light Spirit's useful for free Curaga IVs if he's not acting like an idiot, and for getting Pro/Shell IV if you don't have a WHM. I'll sometimes 2hr my Light Spirit for 3 minutes of main healing without me having to do anything.

FTFY... no such thing as a free lunch when it comes to spirits. They have the highest perpetuation costs of any other summon for a reason (still trying to figure out what that reason is though). At a whopping 18mp/tick, it can eat through a good 5 tics before it fires off that Curaga IV, costing you 100mp but saving you 160mp... then again, it could decide you need Regen instead. Doh!

Best part is that Dark Spirit is the most rare and expensive one... and it has zero use.

Well, it is GREAT in apollyon and dynamis for siphon. So I guess with the addition of siphon SE actually made the cost understandable. But it is still hilarious how something can be expensive 3 years before it has a use.

Then again I bet someone out there are buying niddhog scales just in case.

Other than Elemental Siphon and using them to get away from aggro, I don't think there's much else use for it. Though I do <3 them for those very reasons. I wouldn't call them useless. Elemental Siphon has definitely been the reason I've won some things I probably shouldn't have. And I can't tell you how many times I've used a spirit to get away from aggro.

Although, that LightSpirit.. One time on the way to duo Ifrit, I aggroed a bomb just before the zone to the Cloister. It got me down to 145 HP. The first thing the LightSpirit does.. Hits it, while it takes a hit at me and misses, then the LightSpirit flashed it. That got it's attention, but the silly thing never cured me, while I sat at 145 HP.

It's been said before, but you seem new to Summoner, so you might not know. But at 75 Summoning skill, if over cap, effects the accuracy of your avatar. And some say it helps the AI of Spirits. Though others argue and say it doesn't, but it does effect the casting time between casts.

Though IMO, as useful and life saving as they may be, at 75, personally I still wouldn't use merits on lowering their perpetuation.
